Hello Gents,
This is awful late, but I want to say something about this problem.
I work on EASi OPC30's and ACR OPC's 5400's.
Last summer, I did a diagnosis and repair for a G2 event code.
Pulled the Steer Motor Assembly out, and found that the small diameter Spur Gear (attached to the output shaft of Steer Motor) was worn out.
Installed a New Gear, and the problem was solved.
